Methods, systems, and computer program products for navigating between visual components

ABSTRACT

Methods and systems are described for navigating between visual components. A first visual component, of a first operating application in a plurality of operating applications, is detected in a first application region of a presentation space of a display device. A first navigation control is presented, in a first navigation region determined based on the first application region, for navigating to a second visual component, of a second application in the plurality, in a second application region in the presentation space. A user input corresponding to the first navigation control is detected. In response to the detected user input, navigation information is sent to navigate to the second visual component.

BACKGROUND

Cluttered desktops on desktop, notebook, and handheld devices are common. Navigating among visual components of various applications requires locating a desired visual component in the clutter and/or interoperating with a standard user interface element such as a task bar and/or application menu of a desktop that remains in a single location and requires the same types of inputs and user movements for each application and/or visual component to be located. This may require a user to repeat a similar and/or same set of movements over and over. Further, a task bar or other standard application navigation user interface may be located in a location that is convenient for some applications but inconvenient for others for a user. This creates a lot of input overhead in cases where switching between apps is frequent. Input to bring an app into focus is essentially non-productive input, as it is not related to any of the tasks performed by the applications a user is interacting with.

Accordingly, there exists a need for methods, systems, and computer program products for navigating between visual components.

Elements 104-114 may be operatively coupled by various means. Bus 116 may comprise any type of bus architecture, including a memory bus, a peripheral bus, a local bus, and/or a switching fabric.

IPU 104 is an instruction execution machine, apparatus, or device. Exemplary IPUs include one or more microprocessors, digital signal processors (DSPs), graphics processing units, application-specific integrated circuits (ASICs), and/or field programmable gate arrays (FPGAs). In the description of the subject matter herein, the terms “IPU” and “processor” are used interchangeably. IPU 104 may access machine code instructions and data via one or more memory address spaces in addition to the physical memory address space. A memory address space includes addresses identifying locations in a processor memory. The addresses in a memory address space are included in defining a processor memory. IPU 104 may have more than one processor memory. Thus, IPU 104 may have more than one memory address space. IPU 104 may access a location in a processor memory by processing an address identifying the location. The processed address may be in an operand of a machine code instruction and/or may be identified in a register or other portion of IPU 104.

FIG. 1 illustrates virtual processor memory 118 spanning at least part of physical processor memory 106 and at least part of persistent secondary storage 108. Virtual memory addresses in a memory address space may be mapped to physical memory addresses identifying locations in physical processor memory 106. An address space for identifying locations in a virtual processor memory is referred to as a virtual memory address space; its addresses are referred to as virtual memory addresses; and its processor memory is known as a virtual processor memory or virtual memory. The term “processor memory” may refer to physical processor memory 106 and/or virtual processor memory 118 depending on the context in which the term is used.

Persistent secondary storage may include removable media. The drives and their associated computer-readable storage media provide volatile and/or nonvolatile storage for computer-readable instructions, data structures, program components, and other data for execution environment 102.

Execution environment 102 may include software components stored in persistent secondary storage 108, in remote storage accessible via a network, and/or in a processor memory. FIG. 1 illustrates execution environment 102 including operating system 120, one or more applications 122, and other program code and/or data components illustrated by other libraries and subsystems 124. In an aspect, some or all software components may be stored in locations accessible to IPU 104 in a shared memory address space shared by the software components. The software components accessed via the shared memory address space are stored in a shared processor memory defined by the shared memory address space. In another aspect, a first software component may be stored in one or more locations accessed by IPU 104 in a first address space and a second software component may be stored in one or more locations accessed by IPU 104 in a second address space. The first software component is stored in a first processor memory defined by the first address space and the second software component is stored in a second processor memory defined by the second address space.

Software components typically include instructions executed by IPU 104 in a computing context referred to as a “process”. A process may include one or more “threads”. A “thread” includes a sequence of instructions executed by IPU 104 in a computing sub-context of a process. The terms “thread” and “process” may be used interchangeably herein when a process includes only one thread.

Execution environment 102 may receive user-provided information via one or more input devices illustrated by input device 128. Input device 128 provides input information to other components in execution environment 102 via input device adapter 110. Execution environment 102 may include an input device adapter for a keyboard, a touch screen, a microphone, a joystick, a television receiver, a video camera, a still camera, a document scanner, a fax, a phone, a modem, a network interface adapter, and/or a pointing device, to name a few exemplary input devices.

Input device 128 included in execution environment 102 may be included in device 100 as FIG. 1 illustrates or may be external (not shown) to device 100. Execution environment 102 may include one or more internal and/or external input devices. External input devices may be connected to device 100 via corresponding communication interfaces such as a serial port, a parallel port, and/or a universal serial bus (USB) port. Input device adapter 110 receives input and provides a representation to bus 116 to be received by IPU 104, physical processor memory 106, and/or other components included in execution environment 102.

Output device 130 in FIG. 1 exemplifies one or more output devices that may be included in and/or may be external to and operatively coupled to device 100.

The terms “network node” and “node” in this document both refer to a device having a network interface component for operatively coupling the device to a network. The terms “device” and “node” as used herein further refer to one or more devices and nodes, respectively, providing and/or otherwise included in an execution environment unless clearly indicated otherwise.

The block diagram in FIG. 3 illustrates an exemplary system for navigating between visual components according to the method illustrated in FIG. 2. FIG. 3 illustrates a system, adapted for operation in an execution environment, such as execution environment 102 in FIG. 1, for performing the method illustrated in FIG. 2. The system illustrated includes a presentation space (PS) monitor component 302, an application navigator component 304, a navigation element handler component 306, and a navigation director component 308.

FIG. 1 illustrates components of an exemplary device that may at least partially provide and/or otherwise be included in an execution environment. The components illustrated in FIGS. 4 a-d may be included in or otherwise combined with the components of FIG. 1 to create a variety of arrangements of components according to the subject matter described herein.

FIG. 5 illustrates user node 502 as an exemplary device that in various aspects may be included in and/or otherwise adapted for providing any of execution environments 401 illustrated in FIGS. 4 a-c, each illustrating a different adaptation of the arrangement of components in FIG. 3. FIG. 5 illustrates that user node 502 is operatively coupled to network 504 via a network interface component, such as NIA 114. Alternatively or additionally, an adaptation of an execution environment 401 may include and/or may otherwise be provided by a device that is not operatively coupled to a network. Application provider node 506 may be included in and/or otherwise adapted for providing execution environment 401 d illustrated in FIG. 4 d. As illustrated in FIG. 5, application provider node 506 is operatively coupled to network 504 via a network interface component included in execution environment 401 d.

FIG. 4 a illustrates execution environment 401 a hosting application 403 a including an adaptation of the arrangement of components in FIG. 3. FIG. 4 b illustrates execution environment 401 b hosting browser 403 b including an adaptation of the arrangement of components in FIG. 3 that may operate at least partially in a network application agent 405 b received from a remote application provider, such as network application 403 d in FIG. 4 d. Browser 403 b and execution environment 401 b may provide at least part of an execution environment for network application agent 405 b that may be received via a network from a network application operating in a remote execution environment. FIG. 4 c illustrates an arrangement of the components in FIG. 3 adapted to operate in GUI subsystem 437 c of execution environment 401 c. The arrangement in FIG. 4 c may mediate communication between applications in execution environment 401 c and one or more output devices, such as output device 130 in FIG. 1.

FIG. 4 d illustrates execution environment 401 d configured to host one or more network applications, such as a Web service, illustrated by network application 403 d. FIG. 4 d also illustrates network application platform 409 d that may provide services to one or more network applications. Network application 403 d includes yet another adaptation of the arrangement of components in FIG. 3.

The various adaptations of the arrangement in FIG. 3 are not exhaustive. For example, those skilled in the art will see based on the description herein that arrangements of components for performing the method illustrated in FIG. 2 may be at least partially included in an application and at least partially external to the application. Further, arrangements for performing the method illustrated in FIG. 2 may be distributed across more than one node and/or execution environment. For example, such an arrangement may operate at least partially in browser 403 b in FIG. 4 b and at least partially in execution environment 401 d in and/or external to network application 403 d in FIG. 4 d.

FIGS. 4 a-d illustrate adaptations of network stacks 411 configured for sending and receiving messages over a network, such as network 504, via a network interface component. Network application platform 409 d in FIG. 4 d provides services to one or more network applications. In various aspects, network application platform 409 d may include and/or interoperate with a web server. FIG. 4 d also illustrates network application platform 409 d configured for interoperating with network stack 411 d directly and/or indirectly.

Network stacks 411 may support the same protocol suite, such as TCP/IP, or may communicate via a network gateway or other protocol translation device and/or service. For example, browser 403 b in FIG. 4 b and network application platform 409 d in FIG. 4 d may interoperate via their respective network stacks: network stack 411 b and network stack 411 d.

FIGS. 4 a-d illustrate applications 403, respectively, which may communicate via one or more application layer protocols. FIGS. 4 a-d respectively illustrate application protocol components 413 for communicating via one or more application layer protocols. Exemplary application protocols include hypertext transfer protocol (HTTP) and instant messaging and presence (XMPP-IM) protocol. Matching protocols enabling applications 403 to communicate via network 504 in FIG. 5 are not required, if communication is via a protocol gateway or other translator.

In FIG. 4 b, browser 403 b may receive some or all of network application agent 405 b in one more messages sent from a network application, such as network application 403 d via network application platform 409 d, a network stack 411, a network interface component, and optionally an application protocol component 413. In FIG. 4 b, browser 403 b includes content manager component 415 b. Content manager component 415 b may interoperate with one or more of application protocol components 413 b and/or network stack 411 b to receive the message or messages including some or all of network application agent 405 b.

Network application agent 405 b may include a web page for presenting a user interface for network application 403 d. The web page may include and/or reference data represented in one or more formats including hypertext markup language (HTML) and/or other markup language, ECMAScript and/or other scripting language, byte code, image data, audio data, and/or machine code.

In an example, in response to a request received from browser 403 b in FIG. 4 b operating in user node 502 in FIG. 5, controller component 417 d, in FIG. 4 d, operating in application provider node 506 may invoke model subsystem 419 d to perform request-specific processing. Model subsystem 419 d may include any number of request handlers (not shown) for dynamically generating data and/or retrieving data from model database 421 d based on the request. Controller component 417 d may further invoke template engine component 423 d to identify one or more templates and/or static data elements for generating a user interface for representing a response to the received request. FIG. 4 d illustrates template database 425 d including exemplary template 427 d. FIG. 4 d illustrates template engine 423 d as a component in view subsystem 429 d configured to return responses to processed requests in a presentation format suitable for a client, such as browser 403 b. View subsystem 429 d may provide the presentation data to controller component 417 d to send to browser 403 b in response to the request received from browser 403 b. Some or all of network application agent 405 b may be sent to browser 403 b via network application platform 409 d as described above.

While the example above describes sending some or all of network application agent 405 b in response to a request, network application 403 d additionally or alternatively may send some or all of a network application agent to browser 403 b via one or more asynchronous messages. An asynchronous message may be sent in response to a change detected by network application 403 d. Publish-subscribe protocols, such as the presence protocol specified by XMPP-IM, are exemplary protocols for sending messages asynchronously.

The one or more messages including information representing some or all of network application agent 405 b in FIG. 4 b may be received by content manager component 415 b via one or more of application protocol component(s) 413 b and network stack 411 b as described above. In FIG. 4 b, browser 403 b includes one or more content handler components 431 b to process received data according to its data type, typically identified by a MIME-type identifier. Exemplary content handler components 431 b include a text/html content handler component for processing HTML documents; an application/xmpp-xml content handler component for processing XMPP streams including presence tuples, instant messages, and publish-subscribe data as defined by various XMPP specifications; one or more video content handler components for processing video streams of various types; and still image data content handler components for processing various images types. Content handler components 431 b process received data and may provide a representation of the processed data to one or more user interface (UI) element handler components 433 b.

UI element handler components 433 are illustrated in presentation controller components 435 in FIG. 4 a, FIG. 4 b, and FIG. 4 c. A presentation controller component 435 may manage visual, audio, and/or other types of output of its including application 403 as well as receive and route detected user and other inputs to components and extensions of its including application 403. With respect to FIG. 4 b, a UI element handler component 433 b in various aspects may be adapted to operate at least partially in a content handler component 431 b such as a text/html content handler component and/or a script content handler component. Additionally or alternatively, a UI element handler component 433 in an execution environments 401 may operate in and/or as an extension of its including application 403, such as a plug-in providing a virtual machine for script and/or byte code, and/or may operate external to an interoperating application 403.

FIGS. 6 a-e illustrate respective display presentation spaces 602 of a display in and/or operatively coupled to a device. FIGS. 6 a-e illustrate first app 604-1 visual components and second app 604-2 visual components in respective presentation spaces 602. The various app 604 visual components illustrated in FIGS. 6 a-e are described as user interfaces of various applications 403 and other components illustrated in FIGS. 4 a-d as required in describing the subject matter herein. An app 604 visual component may be provided as a user interface of multiple applications interoperating. For example, an app 604 visual component and/or a visual component included in an app 604 visual component may be presented via interoperation of browser 403 b, network application agent 405 b, and network application 403 d illustrated in FIG. 4 b and FIG. 4 d. Browser 403 b may operate in user node 502 and network application 403 d may operate in application provider node 506. Network application agent 405 b may be provided to user node 502 by application provider node 506 via network 504, as described above.

Various UI elements of applications 403 described above may be presented by one or more UI element handler components 433 in FIGS. 4 a-c and/or by one or more template engines 423 d in FIG. 4 d. In an aspect, illustrated in FIGS. 4 a-4 c, UI element handler component(s) 433 of one or more applications 403 is/are configured to send representation information representing a visual interface element, such as an operation bar 606 in FIG. 6 a and in FIG. 6 d, to a GUI subsystem 437. A GUI subsystem 437 may instruct a graphics subsystem 439 to draw the visual interface element in a region of a respective display presentation space 602, based on representation information received from a corresponding UI element handler component 433.

Input may be received corresponding to a UI element via an input driver 441 illustrated in FIGS. 4 a-c in various adaptations. For example, a user may move a mouse to move a pointer presented in a display presentation space 602 over an operation user interface element presented in an operation bar 606. A user may provide an input detected by the mouse. The detected input may be received by a GUI subsystem 437 via an input driver 441 as an operation or command indicator based on the association of the shared location of the pointer and the operation user interface element in display presentation space 602.

The components of a user interface are generically referred to herein as user interface elements. More specifically, visual components of a user interface are referred to herein as visual interface elements. A visual interface element may be a visual component of a graphical user interface (GUI). Exemplary visual interface elements include windows, textboxes, sliders, list boxes, drop-down lists, spinners, various types of menus, toolbars, ribbons, combo boxes, tree views, grid views, navigation tabs, scrollbars, labels, tooltips, text in various fonts, balloons, dialog boxes, and various types of button controls including check boxes and radio buttons. An application interface may include one or more of the elements listed. Those skilled in the art will understand that this list is not exhaustive. The terms “visual representation”, “visual component”, and “visual interface element” are used interchangeably in this document. Other types of user interface elements include audio output components referred to as audio interface elements, tactile output components referred to as tactile interface elements, and the like.

A “user interface (UI) element handler” component, as the term is used in this document, includes a component configured to send information representing a program entity for presenting a user-detectable representation of the program entity by an output device, such as a display. A “program entity” is an object included in and/or otherwise processed by an application or executable program component. The user-detectable representation is presented based on the sent information. The sent information is referred to herein as “presentation information”. Presentation information may include data in one or more formats. Exemplary formats include image formats such as JPEG, video formats such as MP4, markup language data such as HTML and other XML-based markup, and/or instructions such as those defined by various script languages, byte code, and/or machine code. For example, a web page received by a browser from a remote application provider may include HTML ECMAScript, and/or byte code for presenting one or more user interface elements included in a user interface of the remote application. Components configured to send information representing one or more program entities for presenting particular types of output by particular types of output devices include visual interface elements, audio interface element handler components, tactile interface element handler components, and the like.

A representation of a program entity may be stored and/or otherwise maintained in a presentation space. As used in this document, the term “presentation space” refers to a storage region allocated and/or otherwise provided for storing presentation information, which may include audio, visual, tactile, and/or other sensory data for presentation by and/or on an output device. For example, a buffer for storing an image and/or text string may be a presentation space. A presentation space may be physically and/or logically contiguous or non-contiguous. A presentation space may have a virtual as well as a physical representation. A presentation space may include a storage location in a processor memory, secondary storage, a memory of an output adapter device, and/or a storage medium of an output device. A screen of a display, for example, is a presentation space.

As used herein, the term “program” or “executable” refer to any data representation that may be translated into a set of machine code instructions and optionally associated program data. Thus, a program component or executable component may include an application, a shared or non-shared library, and a system command. Program representations other than machine code include object code, byte code, and source code. Object code includes a set of instructions and/or data elements that either are prepared for linking prior to loading or are loaded into an execution environment. When in an execution environment, object code may include references resolved by a linker and/or may include one or more unresolved references. The context in which this term is used will make clear that state of the object code when it is relevant. This definition can include machine code and virtual machine code, such as Java™ byte code.

As used herein, an “addressable entity” is a portion of a program, specifiable in programming language in source code. An addressable entity is addressable in a program component translated from the source code in a compatible execution environment. Examples of addressable entities include variables, constants, functions, subroutines, procedures, modules, methods, classes, objects, code blocks, and labeled instructions. A code block includes one or more instructions in a given scope specified in a programming language. An addressable entity may include a value. In some places in this document “addressable entity” refers to a value of an addressable entity. In these cases, the context will clearly indicate that the value is being referenced.

Addressable entities may be written in and/or translated to a number of different programming languages and/or representation languages, respectively. An addressable entity may be specified in and/or translated into source code, object code, machine code, byte code, and/or any intermediate languages for processing by an interpreter, compiler, linker, loader, or analogous tool.

Returning to FIGS. 6 a-e, first app 604-1 visual components and second app 604-2 visual components are collectively and generically are referred to as app(s) 604 visual components. App 604 visual components in FIGS. 6 a-e illustrate a number of visual user interface elements commonly found in application user interfaces. Menu bars 608 are illustrated in first app 604-1 visual components in FIGS. 6 a-e. Menu bars 608 are illustrated including menu controls for receiving user input to identify commands to perform. Location bars 609 are illustrated including universal resource locators (URLs) identifying sources of presented data. App 604 visual components also illustrate user interface elements providing respective application presentation spaces 610 for presenting content including other visual components illustrated by resource user interface elements 612-1 d through 612-nd in FIG. 6 d representing respective resources.

With reference to FIG. 2, block 202 illustrates that the method includes detecting, in a first application region of a presentation space of a display device, a first visual component of a first operating application in a plurality of operating applications. Accordingly, a system for navigating between visual components includes means for detecting, in a first application region of a presentation space of a display device, a first visual component of a first operating application in a plurality of operating applications. For example, as illustrated in FIG. 3, presentation space monitor component 302 is configured for detecting, in a first application region of a presentation space of a display device, a first visual component of a first operating application in a plurality of operating applications. FIGS. 4 a-d illustrate presentation space monitor components 402 as adaptations and/or analogs of presentation space monitor component 302 in FIG. 3. One or more presentation space monitor components 402 operate in execution environments 401.

In FIG. 4 a, PS monitor component 402 a is illustrated as a component of application 403 a. In FIG. 4 b, PS monitor component 402 b is illustrated as component of network application agent 405 b. In FIG. 4 c, PS monitor component 402 c is illustrated operating external to one or more applications 403 c. Execution environment 401 c includes PS monitor component 402 c in GUI subsystem 437 c. In FIG. 4 d, PS monitor component 402 d is illustrated operating network application 403 d remote from a display device for presenting and/or updating a visual component. For example, PS monitor component 402 may operate in application provider node 506 while a visual component is presented via a display device of user node 502 based on presentation information sent via network 504 from application provider node 506.

A visual component may be detected by one or more of receiving a request to present the visual component, receiving a request for a resource for presenting the visual component, detecting a change in at least a portion of a presentation space, intercepting a communication identifying the visual component, receiving an input corresponding to the visual component, receiving a notification identifying the visual component, and sending presentation information to present at least a portion of the visual component.

In FIG. 4 a, PS monitor 402 a may receive a request to present a visual component, such as app 604 visual component in any of FIGS. 6 a-e. PS monitor component 402 a may be configured to intercept and/or otherwise mediate access to one or more UI element handler components 433 a for presenting the app 604 visual component and/or other visual components of application 403 a. PS monitor component 402 a may send presentation information and/or information for generating presentation information to a UI element handler component 433 a for presenting some or all of a visual component via a display device.

In FIG. 4 b, PS monitor component 402 b may receive, intercept, and/or otherwise mediate processing of a request for a resource for presenting a visual component such as a browser tab, a browser window of browser 403 b, and/or content received from network application 403 d in FIG. 4 d operating in application provider node 506. Content from network application 403 d may include network application agent 405 b and/or content retrieved by network application agent 405 b. PS monitor component 402 b may be a component of browser 403 b. Alternatively or additionally, a PS monitor component 402 may operate as a component of network application agent 405 b and/or a component of network application 403 d as illustrated by PS monitor component 402 d.

PS monitor component 402 c in FIG. 4 c may track and/or otherwise monitor at least some changes to a presentation space accessible to GUI subsystem 437 c. FIGS. 6 a-e illustrate various display presentation spaces 602 and application presentation spaces 610 as exemplary presentation spaces. A change to a presentation space may include presenting a visual component via the presentation space, updating a visual component in the presentation space, and/or removing a visual component from the presentation space. A change may be in response to a user input. PS monitor component 402 c may receive and/or otherwise monitor user input received for a visual component. In an aspect, PS monitor component 402 c may receive change information by accessing a log maintained by GUI subsystem 437 c and/or graphics subsystem 439 c. The log may be accessed via receiving notifications of log entries.

As described above, a visual component may be detected by an application presenting some or all of the visual component, by a remote node, and/or by a component operating external to an application that presents some or all of the visual component.

In detecting and/or otherwise monitoring a visual component, a PS monitor component 402 may identify a region in a presentation space that includes the visual component. The region is referred to herein as an “application region”. As illustrated in FIGS. 6 a-e a visual component may be included in a plurality of visual components in a presentation space. The visual components may be included in user interfaces of a plurality of operating applications.

Returning to FIG. 2, block 204 illustrates that the method further includes presenting a first navigation control, in a first navigation region determined based on the first application region, for navigating to a second visual component, of a second application in the plurality, in a second application region in the presentation space. Accordingly, a system for navigating between visual components includes means for presenting a first navigation control, in a first navigation region determined based on the first application region, for navigating to a second visual component, of a second application in the plurality, in a second application region in the presentation space. For example, as illustrated in FIG. 3, application navigator component 304 is configured for presenting a first navigation control, in a first navigation region determined based on the first application region, for navigating to a second visual component, of a second application in the plurality, in a second application region in the presentation space. FIGS. 4 a-d illustrate application navigator components 404 as adaptations and/or analogs of application navigator component 304 in FIG. 3. One or more application navigator components 404 operate in execution environments 401.

A navigation control is a user interface element for navigating between and/or among user interface elements of respective operating applications. The user interface elements may be visual components. A navigation control may include and/or have an application control representing a particular application. An application control may include and/or have a visual component control representing a particular visual component in the application represented by the application control. An input received corresponding to a particular application control may identify a user instruction to navigate to a visual component of the particular application. A user input corresponding to a particular visual component control may identify a user instruction to navigate to a particular visual component in a particular application corresponding to an application control that includes and/or otherwise has the visual component control.

FIGS. 6 a-e illustrate various navigation control 614 visual components. Second navigation control 614-2 a illustrates a user interface element that is a parent of second app 604-2 a visual component. Navigation control 614-2 a includes and illustrates first application control 616-1 a, second application control 616-2 a, and third application control 616-3 a. First app 604-1 a visual component may be included in a user interface for a first application, second app 604-2 a visual component may be included in a user interface for a second application, and a third app visual component (not shown) may be included in a user interface for a third application.

A navigation control may be automatically presented in response to presenting of a corresponding visual component in a user interface of an operating application. For example, as described, second navigation control 614-2 a includes second app 604-2 a visual component of a second application. In FIG. 4 c, GUI subsystem 437 c may receive presentation information for presenting second app 604-2 a visual component. GUI subsystem 437 c may invoke application navigator component 404 c. Application navigator component 404 c may provide a presentation space for presenting second app 604-2 a visual component in second navigation control 614-2 a by instructing navigation element handler component 406 c to present second navigation control 614-2 a in display presentation space 602 a.

In another aspect, a navigation control may be presented in response to a navigation-activate input received from a user via an input device. For example, first app 604-1 b visual component in FIG. 6 b may be presented by browser 403 b in FIG. 4 b. First navigation control 614-1 b may be non-existent and/or hidden until a navigation-activate input is received by application navigator component 404 b via a UI element handler component 433 b. The input may be a hotkey, a touch in a designated location of a touch screen, and/or a mouse gesture defined as a navigation-activate input. Alternatively or additionally, a pointer user interface element presented within a specified distance of, for example, the top, right corner of first app 604-1 b visual component may be detected as a navigation-activate input. A navigation-activate input may be defined by a particular application such as application 403 a in FIG. 4 a and/or browser 403 b in FIG. 4 b. In another aspect, a navigation-activate input may be defined for an execution environment. For example GUI subsystem 437 c may include and/or otherwise access configuration information defining a navigation-activate input for applications operating in execution environment 401 c. Further, a navigation-activate input may be defined and/or detected by a node remote from a node detecting the input. Application navigator component 404 d and navigation element handler component 406 d operating in application provider node 506 may define and/or may detect a navigation-activate input via browser 403 b and/or network application agent 405 b operating in user node 502.

An application navigator component 404 may determine and/or otherwise identify a region, in a presentation space, to present a navigation control 614. The navigation region may be determined based on an application region as described above. A region including a navigation control is referred to herein as a “navigation region”. As illustrated in FIGS. 6 a-e, a navigation region may be determined based on an application region in various ways. FIG. 6 a illustrates navigation control 614-2 a in a navigation region that includes the application region of second app 604-2 a visual component. FIG. 6 b illustrates navigation control 614-1 b in a navigation region determined based on the top, right corner of the application region for first app 604-1 b visual component. FIG. 6 c illustrates navigation control 614-1 c in a navigation region based on a portion of a left border of the application region that includes first app 604-1 c visual component. FIG. 6 d illustrates navigation control 614-2 d in a navigation region as a pop-up or context pane where the navigation region may be determined based on a location corresponding to an input detected in the application region including second app 604-2 d visual component. FIG. 6 e illustrates navigation control 614-1 e in a navigation region bound to menu bar 608-1 e in the application region that includes first app 604-1 e visual component.

Returning to FIG. 2, block 206 illustrates that the method yet further includes detecting a user input corresponding to the first navigation control. Accordingly, a system for navigating between visual components includes means for detecting a user input corresponding to the first navigation control. For example, as illustrated in FIG. 3, navigation element handler component 306 is configured for detecting a user input corresponding to the first navigation control. FIGS. 4 a-d illustrate navigation element handler component 406 as adaptations and/or analogs of navigation element handler component 306 in FIG. 3. One or more navigation element handler components 406 operate in execution environments 401.

In an aspect, an input may be detected by a navigation element handler component 406 in FIGS. 4 a-d. The navigation element handler component 406 may determine a second visual component based on an ordering of applications and/or their respective visual components maintained by a corresponding application navigation component 404. For example, an ordering may be based on a z-level of visual components, a priority assigned to an application process providing a context for an operating application, a priority and/or other attribute of a thread in an application process, and/or a user-specified ordering. In an aspect, a navigation element handler component 406 and/or an application navigation component 404 b may identify an application and/or a visual component of an application randomly. For example, applications and/or visual components may be assigned numbers and a random number generator may be invoked to identify an application and/or visual component identified by a number generated by the random number generator.

Detecting a user input corresponding to a navigation control may include detecting the user input corresponding to an application control included in and/or otherwise associated with the navigation control. A navigation control may include one or more application controls corresponding to one or more respective applications. In another aspect, an application control corresponding to a particular application may be included in a navigation control. A user input may be detected corresponding to a particular application control in a navigation control. The application control identifies an application. A navigation element handler component 406 may interoperate with an application navigation component 404 to identify a visual component of the application 403, such as the application's main window, a visual component most recently updated, and/or a visual component assigned input focus for an input device.

Detecting a user input corresponding to a navigation control may include detecting the user input corresponding to a visual component control included in and/or otherwise associated with the navigation control. A visual component control may be included in and/or otherwise associated with an application control corresponding to an application of a visual component corresponding to the visual component control. A navigation control and/or an application control may include one or more visual component controls corresponding to one or more respective visual components. A visual component control may be included in an application control, corresponding to a particular application, included in a navigation control. A user input may be detected corresponding to a particular visual component control in a navigation control. The visual component control identifies a particular visual component in a particular application. A navigation element handler component 406 may interoperate with an application navigation component 404 to identify the visual component of the application.

A navigation element handler component 406 may determine and/or otherwise detect an input corresponding to a navigation control 614. As illustrated in FIGS. 6 a-e, a navigation control may be presented in various ways. A navigation control as illustrated in FIGS. 6 a-e may include an application control 616 and/or a visual component control 618.

FIG. 6 a illustrates first application control 616-1 a, second application control 616-2 a, and third application control 616-3 a in second application control 614-2 a. FIG. 6 b illustrates first application control 616-1 b, second application control 616-2 b, and third application control 616-3 b as menu items and/or submenus in navigation control 614-1 b presented as a menu. FIG. 6 c illustrates first application control 616-1 c, second application control 616-2 c, and third application control 616-3 c as first level nodes in navigation control 614-1 c presented as a tree view user interface control. FIG. 6 c also illustrates three visual component controls 618-1 c, 618-2 c, 618-3 c as child nodes of second application control 616-2 c. FIG. 6 d illustrates first application control 616-1 d, second application control 616-2 d, and third application control 616-3 d as first level nodes in navigation control 614-2 d presented as a tree view context user interface control. FIG. 6 d also illustrates three visual component controls 618-1 d, 618-2 d, 618-3 d as child nodes of second application control 616-2 d. FIG. 6 e illustrates no application control for first app 604-1 e visual component. FIG. 6 e illustrates second application control 616-2 e and third application control 616-3 e as menu items and/or submenus in navigation control 614-1 e. FIG. 6 e also illustrates three visual component controls 618-1 e, 618-2 e, 618-3 e as a child menu items of third application control 616-3 e.

An application navigation component 404 may invoke one or more navigation element handler components 406 to present and/or detect input for respective application controls and/or visual component controls.

Returning to FIG. 2, block 208 illustrates that the method yet further includes sending, in response to detecting the user input, navigation information to navigate to the second visual component. Accordingly, a system for navigating between visual components includes means for sending, in response to detecting the user input, navigation information to navigate to the second visual component. For example, as illustrated in FIG. 3, navigation director component 308 is configured for sending, in response to detecting the user input, navigation information to navigate to the second visual component. FIGS. 4 a-d illustrate navigation director components 408 as adaptations and/or analogs of navigation director component 308 in FIG. 3. One or more navigation director components 408 operate in execution environments 401.

Sending the navigation information may include sending the navigation information by invoking a function, a method, and/or a subroutine. Sending the navigation information may include sending the navigation information by sending a message via a network. The message may be sent asynchronously. The message, in another aspect, may be included in a request/response exchange. Sending the navigation information may include sending the navigation information by sending data via an inter-process communication (IPC) including, for example, a message queue, a pipe, an interrupt, a semaphore, and/or a lock. Sending the navigation information may include sending the navigation information via a shared data area.

Navigation information may include information for changing an attribute of a visual component. For example, a z-order attribute, an input focus attribute, a size attribute, a location attribute, a font, a color, and/or a transparency level may be changed based on navigation information for a visual component being navigated to and/or a visual component being navigated from.

In FIG. 4 a, navigation director component 408 a may send navigation information to a specified message queue in execution environment 401 a. Applications operating in execution environment 401 a may subscribe to and/or poll the message queue to receive a navigation instruction. Navigation information may identify a visual component and/or an application to navigate to. An identified application may determine a visual component to navigate to if a visual component of the application is not identified by the navigation information.

In FIG. 6 a, first app 604-1 a visual component may be included in a user interface for application 403 a in execution environment 401 a. An input corresponding to second application control 616-2 a may be detected by navigation element handler component 406 a. Navigation element handler component 406 a, application navigation component 404 a, and/or navigation director component 408 a may generate navigation information based on second application control 616-2 a. Navigation director component 408 a may post the navigation information to a message queue, write the navigation information to a pipe configured for exchanging navigation information between and/or among applications, and/or store the navigation information in a shared data area accessible to other applications in execution environment 401 a. A second application may receive the navigation information and determine that the navigation information identifies the second application. The second application may update second app 604-2 a visual component, for example, so that it is presented on top of first app 604-1 a visual component as shown in FIG. 6 a. The second application may determine a visual component of a user interface of second application to which to navigate. The determination may be user configurable and/or determined by execution environment 401 a.

In FIG. 4 b, navigation director component 408 b may operate as described above. Alternatively or additionally, navigation director component 408 b operating in user node 502 may send a message via network 504 to a remote node, such as application provider node 506. Network application 403 d may provide a subscription service. Navigation director component 408 b may send navigation information to a specified publish-subscribe tuple and/or service. Applications operating in execution environment 401 a may subscribe to and/or poll the tuple and/or service to receive navigation information. Navigation information may identify a visual component and/or an application to navigate to. An identified application may determine a visual component to navigate to if a visual component of the application is not identified by the navigation information. In FIG. 6 b, first app 604-1 b visual component may be included in a user interface for browser 403 b in execution environment 401 b. An input corresponding to first visual component control 618-1 b associated with third application control 616-3 b as illustrated may be detected by navigation element handler component 406 b. Navigation element handler component 406 b, application navigation component 404 b, and/or navigation director component 408 b may generate navigation information based on first visual component control 618-1 b. Navigation director component 408 b may post the navigation information via an asynchronous message to the specified tuple and/or service. The tuple and/or service may be accessible to other applications in execution environment 401 b via a subscription and/or via polling for navigation information.

A second application may receive the navigation information and determine that the navigation information identifies a third application. The second application may ignore the navigation information or may change an attribute of a visual component in a user interface of the second application in accordance with the instruction to navigate to the identified visual component of the third application. The third application may update a third app visual component. The third app visual component may be minimized prior to processing the navigation instruction, may be hidden behind another visual component, and/or may otherwise not be visible to a user. The third application may present the visual component identified by visual component control 618-1 b according to the navigation instruction represented in and/or by the navigation information.

In an aspect, an input detected corresponding to a navigation control may be communicated by user node 502 to network application 403 d operating in application provider node 506. The input information may be received by navigation element handler component 406 d. The navigation control presented by user node 502 may be presented based on presented information provided by application navigation component 404 d based on visual components detected by PS monitor component 402 d interoperating with user node 502. Navigation director component 408 d may send the navigation information to any number of requesting and/or otherwise identified client nodes, such as user node 502. In another aspect, navigation director component 408 d may determine a node to receive the navigation information. Navigation director component 408 d may send the navigation information to the node identified by the determination. Navigation director component 408 d may send the navigation information in an unsolicited message via an asynchronous message and/or may send the navigation information in response to a request from the identified node.

In FIG. 4 c, navigation director component 408 c may send navigation information by invoking a function, method, subroutine, and/or other addressable instruction in an application identified based on the detected input corresponding to a navigation control. Applications operating in execution environment 401 c may register an invocation point with GUI subsystem 437 c. Registration may be explicit and/or implicit in an interoperation between an application 403 c and GUI subsystem 437 c. Navigation information may identify a visual component and/or an application to navigate to. An identified application may determine a visual component to navigate to if a visual component of the application is not identified by the navigation information. In FIG. 6 c, first app 604-1 c visual component may be included in a user interface for an application 403-1 c in execution environment 401 c. An input corresponding to second application control 616-2 c may be detected by navigation element handler component 406 c. Navigation element handler component 406 c, application navigation component 404 c, and/or navigation director component 408 c may generate navigation information based on second application control 616-2 c. Navigation director component 408 c may invoke second application 403-2 c providing access to the navigation information via the invocation. Second application 403-2 c may receive the navigation information and determine a visual component to navigate to if one is not identified in the navigation information. The second application may update second app 604-2 c visual component by moving it from behind first app 604-1 c visual component.

In another aspect, navigation director component 408 c may invoke first application 403-1 c, instructing first application 403-1 c to change a transparency level of first app 604-1 c visual component allowing second app 604-2 c visual component to be visible to a user. Navigation director component 408 c may assign input focus for one or more input devices to the visual component of second application 403-2 c so that input from the one or more input devices is routed to second application 403-2 c and corresponds to the visual component according to the navigation instruction of the navigation information. In various aspects, one or both of first application 403-1 c and second application 403-2 c may be sent navigation information. In another aspect, neither first application 403-1 c nor second application 403-2 c may be sent navigation information. Rather, navigation information may be sent to a component of GUI subsystem 437 c. For example, GUI subsystem 437 c may change the transparency level of first app 604-1 c visual component and assign input focus to second app 604-2 c visual component in navigating to second app 604-2 c visual component.

As described above, in response to navigating to a visual component, a navigation control, in a navigation region determined based on the application region of the visual component, may be presented for navigating from the visual component to another visual component. Thus some or all visual components of some or all operating applications in an execution environment may be presented with a navigation control for navigating to another visual component of the same and/or of a different application.

The method illustrated in FIG. 2 may include additional aspects supported by various adaptations and/or analogs of the arrangement of components in FIG. 3. In various aspects, a visual component may be included in and/or may include window, a dialog box, a textbox, a check box, a radio button, a slider, a list box, a drop-down list, a spinner, a menu, a menu item, a toolbar, a ribbon, a combo box, a tree view, a grid view, a navigation tab, a scrollbar, a label, a tooltip, a balloon, a slide-out control, a pop-up, a pop-over, a pop-under, and a sidebar, to name a few examples.

A first application presenting a first visual component may operate in a first process in an execution environment and a second application presenting a second visual component may operate in a second process in the execution environment. Further, the first and second application may be generated from different source code. The first application may be represented in a processor memory by at least a portion of a first program generated from first source code and the second application may be represented in a processor memory by at least a portion of a second program generated from second source code

Detecting a visual component may include detecting a measure of visibility of the first visual component to a user. A measure of visibility may be based on at least one of a z-order, an attribute of a font, a size, a location in the presentation space, a transparency attribute, and/or a size of a visible portion of a visual component. For example, in FIG. 4 c PS monitor component 402 c may receive information identifying a measure of visibility for any visual component processed by GUI subsystem 437 c.

A navigation control for a visual component may be presented in response to a change detected in a visually detectable attribute of the visual component. For example, an application navigator component 404 in FIGS. 4 a-d may be configured to hide a navigation control 614 in response to maximizing a corresponding app 604 visual component in a user interface of an application 403. When the app 604 visual component is restored to its non-maximized state, the application navigation component 404 may present a navigation control 614 for the app 604 visual component. The navigation control 614 may be presented automatically in response to an input and/or other instruction to present the app 604 visual component in its normal state, neither minimized nor maximized.

A navigation region may be determined based on a location of a visual component, a parent visual component of the visual component, and a child visual component of the visual component. For example, in FIG. 6 a an application navigation component 404 in FIGS. 4 a-d may determine a navigation region for second navigation control 614-2 a where second navigation control 614-2 a is a parent of second app 604-2 a visual component and includes an application region of the visual component, second app 604-2 a. FIG. 6 b illustrates that an application navigation component 404 may determine a navigation region including navigation control 614-1 b where the navigation region is adjacent to the application region of first app 604-1 b visual component. FIG. 6 e illustrates that an application navigation component 404 may determine a navigation region based on menu bar 608-1 e included as a child visual component in first app 604-1 e visual component.

A navigation region may be determined based on a border of a visual component, a parent visual component of the visual component, and a child visual component of the visual component. FIG. 6 b and FIG. 6 c illustrate navigation regions for navigation control 614-1 b and navigation control 614-1 c respectively determined based on a border of first app 604-1 b visual component and first app 604-1 c visual component. FIG. 6 b and FIG. 6 c further illustrate that a navigation region may share a border with an associated application region, may be at least partially included in the application region, and may be outside the application region.

In an aspect, a navigation control and/or an associated visual component may be at least partially transparent. A transparency attribute of the navigation control and/or the visual component may be responsive to a change in a position of a visual representation of an input pointer, a change in an input focus attribute associated with at least one of the navigation control and the visual component, and/or a transparency attribute of the respective visual component and/or the navigation control. A navigation element handler component 406 in FIGS. 4 a-d may be configured to manage the transparency of a navigation control and may further interoperate with a UI element handler component 433 and/or a graphics subsystem 439 to manage transparency of a corresponding visual component.

Presenting a navigation control may include detecting the navigation control presented in a previous navigation region determined based on a corresponding application region. Presenting may further include detecting a move indication (in response to a detected user input), and determining the navigation region based on at least one of a current application region and the previous navigation region. A navigation region may be determined based on the move indication. Further, presenting the navigation control may include determining that a corresponding application region differs from a previous application region in the presentation space, which includes a visual component that corresponded to the navigation region prior to the presenting. Presenting may further include presenting the navigation control in the navigation region from a previous navigation region determined based on the previous application region.

For example, an application navigation component 404 and/or a navigation element handler component 406 may be configured to minimize movement of a navigation control 614 and present the navigation control 614 along a border of a corresponding visual component. When the visual component is moved and/or resized, the application navigation component 404 and/or a navigation element handler component 406 determine a navigation region to include the moved and/or resized navigation control 614 based on the previous navigation region and based on the new application region. Alternatively or additionally, a first input may indicate that a navigation control is to be presented adjacent to a first border of a visual component and a second input may indicate that the navigation control is to be presented as a child visual component of the visual component.

As described above, an application control and/or a visual component control may be included in and/or activated for receiving input based on a state of a corresponding application and/or a state of a visual component of the corresponding application. A state may indicate that an application and/or a visual component is minimized, hidden, partially hidden, suspended, blocked, and/or that access is not authorized.
